Detailed Solution
Download Solution PDFThe correct answer is Gallium
Key Points
- Gallium is the element whose properties matched up remarkably well with eka-aluminium according to Mendeleev's Periodic Table.
- Mendeleev had predicted the existence and properties of eka-aluminium, which was later discovered and named gallium.
- Gallium's properties such as its density, melting point, and the formation of a hydroxide were very close to Mendeleev's predictions for eka-aluminium.
Additional Information
- Dmitri Mendeleev created the Periodic Table and predicted the existence of elements that were not yet discovered.
- He used the properties of known elements to predict the properties of the undiscovered ones, demonstrating the periodic trends in the elements.
- Gallium was discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875.
- The discovery of gallium and its properties were a significant validation of Mendeleev's periodic table.
